I can say from personal experience that being diagnosed with autism spectrum disorder can feel very isolating. Increasingly, however, it’s not unusual.

In the U.S., 1 in 31 children are diagnosed with autism each year by age 8, according to the latest data from the Centers for Disease Control and Prevention. That number, released in April 2025, is up from 1 in 36 in 2023.
